Here's a little thought experiment I had.

120 stars + 70 stars + 16 stars + 1 star + 0 stars makes for a total of 207.5 stars. Now I hear you say "a star is a star, you can't say it's only half", but for the sake of this topic, let's say that 0.5 is to include 0 stars in the count.

Once I get to learning 120 stars (damn those 100 coin routes), I was thinking of doing some sort of All Main Categories % run, where each categories requirements have to be met back to back. The rules are, complete the game once for each main category : start from a new file, do a 0 stars run, beat Bowser and collect final star, then reset to a new file, rinse and repeat for 1, 16, 70... All five categories completed in a row, in any order, for a single total RTA time.

So far, my PBs suggest I could get sub 4-hour, but I'd definitely still need to improve my long categories. I was wondering if any top runner had ever done this before? Dowsky is the only one I see on the website who has submitted top times for all categories. His sum of PBs is around a 2 hours 58 minutes. Imagine how crazy doing a sub 3 hours would be! Weegee also comes to mind since he only lacks a 0 stars run time. Starting with around 15 minutes to do both decent 0 and 1 star runs, and by combining a 1h40 120 stars, 48-min 70 stars, and 16-min 16 stars, there would be 1 minute to spare to get a sub 3-hour time.

I know it might sound dumb. Almost like asking someone to sprint a 100m, then run a 400m, a 5km, and end it with a half-marathon and a full marathon, all at once. Probably not worth a category extension, even though some of them are already pretty dumb, but I'd be really interested to see how the most well-rounded speedrunners would perform. Someone who is both insane in short categories and has the endurance for long categories, able to do it all in one continuous run.
